Abstract

The bird strike to small aircraft has not been an issue because of its low speed and usage as a private aircraft. So, the compliance of the bird strike regulation is limited to large fixed-wing aircraft such as the commuter category in FAR Part 23 and the civil aircraft in FAR Part 25, generally. However, the forecast of dramatic increasing of VLJ(Very Light Jet), the usage of a composite material for an aircraft structure and flight time of general aviation due to Air-taxi for the point to point transportation, would rise up the need of bird strike regulations and a safety enhancement in normal and utility categorized aircraft. In this study, the safety of bird strike to small aircraft wing leading edge made of a metal and a composite material were compared using the explicit finite element analysis.

현재까지 소형항공기의 조류충돌 문제는 상대적으로 낮은 비행속력과 개인용 목적의 운용 탓에 항공기 개발 및 운용 시의 중요 문제로 다루어지지 않았다. 따라서 일반적으로 FAR 23의 커뮤터급이나 FAR 25급 중, 대형 항공기와 달리 조류충돌에 대한 안전성 입증 규정이 적용되지 않았던 게 사실이다. 그러나 지점 간 운송수단인 에어택시(Air-taxi)로의 활용과 충격에 상대적으로 취약한 복합재료의 구조재료로의 적용이 확대된 VLJ(Very Light Jet)의 급격한 수요 증가에 대한 예측은 FAR 23 일반 및 실용기급 항공기의 조류충돌에 대한 안전성 향상에 대한 필요성을 증대시키는 원인으로 작용할 것이다. 본 연구는 복합재로 제작된 주익의 조류충돌 안전성 및 구조효율성을 평가하기 위해 복합재와 금속재가 적용된 소형항공기의 주익 앞전의 조류 충돌시의 안전성에 대한 외연적 유한요소 해석 결과를 비교하는 과정을 담고 있다.
